Observations reveal magnetization reversal mechanisms in permalloy thin films, suggesting differing magnetic behaviors.

The aim is to observe the magnetic anisotropy and magnetization reversal in local regions of a permalloy thin film.
Used Lorentz microscopy to analyze magnetic properties
Focused on local regions of the permalloy film
Compared findings with coherent rotation theory
Identified a different magnetization reversal mechanism than predicted by coherent rotation theory
Explained differences using micromagnetic theory

Hibino et al. (1971) studied this question.
